Answer:

9.5

Step-by-step explanation:

To get the square root of 90 we can use a calculator or prime factorization.

The prime factorization method is given by :

90 = 2 × 3 × 3 × 5

90 = 2 × 3² × 5

Square root of 90 = 3 × square root of 10

That is : 3 × (10)^½

From the calculator we can get:

10^½ = 3.162

The square root of 90 = 3.162 × 3 = 9.486

This is the approximate square root of 90.

The question requires that we give this answer to one decimal place therefore the square root of 90 to on decimal place is :

9.5
